When space makes you dizzy:
Landing a spaceship is not a good time for a pilot to feel
dizzy.
It's easy to tell which way is up and which way is down...or
is it? In the freefall of space travel, there's no pull of gravity to tell your body which way is which. Most astronauts and cosmonauts experience some motion sickness when they first arrive in orbit. NASA is studying why.

Questions and Comments from Visitors
I suggest caution in where an atomic clock is tested on the space
station. A good reference point is probably the space station center
of gravity. Clocks in free fall from 6000 miles and GPS clocks in orbit at 12000 miles both weightless gave the same readings while clocks on MIR were different.

What are the possibilities and limitations of space travel within and beyond our solar system?
asked by Ayamnemon
The following links may be of help to you, if this is for research. If you are asking for my personal opinion or philosophy, it is, "The possibilities of space travel are endless and certain; the limitations of these space travels are only dictated and limited by our minds."
Thanks for stopping by! Hope these links offer help:
